In the beginning of January, iBookBinidng.com started updating a constellation of its most popular posts — lists of bookbinding workshops and classes in different countries. The first one that is almost updated already is Bookbinding Workshops / Classes in the UK (2016).
If you have some additions to the lists mentioned above or you know (or teach) some courses in other countries, please comment below. There will be more lists at iBookBinding.com soon! =)
